Title: Electrical well logging device
Inventor: ALBRIGHT JAMES CURTICE
IPC: F16L1/10
Filed: 1961-06-19
Abstract: 979, 223. Borehole logging equipment. CONTINENTAL OIL CO. June 19, 1961, No. 22077/61. Heading G1N. A method of producing a record of variations in the sub-geological strata of a borehole by simultaneously recording signals from a pair of sondes, comprises receiving signals corresponding to the received voltages and transmitted currents of the two sondes, forming ratios for each sonde of the two signals from the respective sondes, adjusting the signals to compensate for the difference in depth between the two sondes and forming a third ratio with the two sonde ratio signal voltages. Two or more logging devices 13, 14, 15 and 20, 31, Fig. 1 in a common sonde, transmit distinctive signals i.e. of different frequencies or in different time positions whereby different records dependent upon the investigation being carried out by the individual devices are simultaneously produced. The sonde also includes a self-potential measuring electrode 35 and a well-bore calliper in which the wiper of a potentiometer 34 is positioned by arms 28, 29 carrying pad electrodes. The currents i d  is, from sources 45, 60 transmitted by the devices, which are of the focussing type and produce different penetration; and the potentials e d  e, from a remote pick-up electrode 16, are applied via frequency selective amplifiers 50, 57, 70, 72 to frequency modulated transmitters 51, 58, 71, 73 respectively which are matched by networks T 1-4 , for return of the signals to measuring and recording apparatus at the surface. The sonde equipment is energized over cable 12 via a power supply unit 43, a capacitor 41 providing protection from direct current in conductor 12 and filter 42 blocking other signalling frequencies. The frequency modulated signals are applied to the conductor 12 over a high-pass filter 55 together with a frequency modulated signal from the calliper. At the surface the voltage and current signals from the respective generators are applied to respective ratio detectors 99 and 105, Fig. 2, the output from the former, after rectification passing through a delay network 101 which compensates for height differences between the devices. The two ratios (e/i) d  and (e/i) s  are recorded in instruments 102, 107, and a ratio of the ratios is obtained in unit 108 the output from this too being recorded. An arrangement having separate lines to convey the various signals is described with reference to Fig. 3 (not shown).

Title: Improvements in or relating to transposing heads for use in the manufacture of transposed multiple strip conductor
Inventor: HINDS RONALD
IPC: H01B13/02
Filed: 1962-06-07
Abstract: 963,838. Transposed conductor stranding machines. BRITISH INSULATED CALLENDER'S CABLES Ltd. June 6, 1963 [June 7, 1962], No. 22090/62. Addition to 920,532. Heading H1A.  A transposing head is described which is similar to that disclosed in the parent Specification and which is intended to be mounted and used in the same way for the production of transposed multiple strip electrical conductors. The head comprises a pair of fingers 60 movable in directions (vertical as shown) at right angles to the axis of a closing die through which the conductor strips pass and a second pair of fingers 68 movable in directions (horizontal as shown) at right angles to that of the fingers 60. Each finger is mounted adjustably on a carrier 57 and each carrier is pivotally mounted on a carrier base 36 adapted to be moved through ring cam means (not shown) and rocker arms 52 towards or away from the die. Tension springs (Fig. 2, not shown) bias the carrier bases 36 outwards from the die. The vertically movable fingers 60 are mounted for longitudinal adjustment on the respective carriers 57 while the fingers 68 are laterally or pivotally adjustable on their carriers 57 to accommodate varying numbers and sizes of conductor strip. A pair of short straight links 76 (Fig. 2, not shown) couple the vertically movable carriers with the adjacent horizontally movable carriers and a pair of longer curved links 75 (Fig. 2, not shown) couple the horizontal carriers 57 respectively with the vertically movable base 36 which is associated with the same stack of conductor strips. The links 75, 76 ensure the correct positioning and engagement of the fingers 60, 68 with the four corner conductor strips and furthermore ensure that when transposition of a conductor strip or displacement of a stack of strips takes place complementary movement of an adjacent finger takes place also. The fingers 68 are notched asymmetrically at their ends 72 and may be turned over to provide additional adjustment for varying sizes of conductor being produced.

Patent GB-655552-A (GB)
Title: Fluid pressure control device
IPC: B60T13/14
Filed: 1947-08-08
Abstract: 655,552. Fluid-pressure brakes. BENDIX AVIATION CORPORATION. Aug. 8, 1947, No. 22131. Convention date, March 23, 1946. [Class 103 (i)] A master cylinder for a fluid-pressure braking system having a connection 80 to the wheel brake cylinders and a connection 84 to a reservoir and which is operated by outward movement of the pull rod 54, attached to a brake pedal or the like, has a system of valves and pistons so arranged that any pressure applied to the wheel cylinders by operation of rod 54 is automatically boosted up in a predetermined ratio by fluid supplied through connection 106 from an accumulator or other pressure storage vessel. When rod 54 is moved to the left, it first closes the valve 52 and then draws with it the piston 40 so that fluid from chamber 44 is delivered by port 78 and connection 80 to the wheel brake cylinders in the normal way. Fluid from chamber 44 is, however, also delivered by passage 82 against one end of a piston 68 which is moved to the right, in so doing first cutting off the supply from the reservoir connection 84 by shutting valve 92 and then opening valve 114 to permit pressure fluid from the accumulator connection 106 to enter chamber 76 and pass through port 94 to the right of piston 40, thereby applying a servo effort to the pull on rod 54. The resulting increased pressure in chamber 44 to the left of piston 40 tends to move the piston 68 further to the right to repeat the cycle of operations. The movement of piston 68 is, however, finally stabilized when the pressure in chamber 76 acting against the larger end 72 of piston 70 balances the pressure in chamber 74 at the other end It can be shown that the pressure in chamber 76 and therefore, to the right of piston 40, at which equilibrium is established, depends upon a constant equal to the ratio A3A2/A4A1, where A1 and A2 are the effective areas of the larger and smaller ends of piston 68 and A3 and A4 the effective areas at each side of piston 40. If the said ratio is greater than unity the boost pressure is uncontrollable up to the maximum supplied by the accumulator, but by so designing the piston 68 that it is a value less than unity specified power boost ratios may be obtained. The master cylinder may be used for applications other than brakes.

Title: Improvements in electric signalling systems
IPC: H02J13/00
Filed: 1935-08-06
Abstract: 460,904. Electric signalling systems. STANDARD TELEPHONES & CABLES, Ltd., and McWHIRTER, E. M. S. Aug. 6, 1935, No. 22172. [Class 40 (i)] [Also in Groups XXXVI and XL] Lamps are connected across fuses to give an alarm when a fuse blows, the radiation from the lamp affecting a light-sensitive cell which either controls a local alarm or initiates transmission of a signal to a central station. As shown in Fig. 1, the lamps 8, 9, &c. are connected across fuses F, the lamps being arranged around a cell 13. When one of the fuses blows, the corresponding lamp is lit and the cell 13 is energized to give an alarm. If the alarm is to be given at a central station, the signalling system as shown in Fig. 2 may be used. When the cell 13 is energized, the relay LR (not shown) pulls up and connects tapped resistance R1, R2 to line. At the main station relay AR is energized to light alarm lamp AL and ring alarm bell AB. To determine at which station the fuse is blown, contacts IK are changed over and the selector switch steps until the relay IR is balanced. As the resistances R1, R2 are tapped at different points at the different stations, the position of the switch indicates the station at which the fuse is blown and this position is revealed by lamps 1, 2 ... 10.

Title: Improvements in photographic dye imbibition processes
IPC: G03C7/25
Filed: 1958-07-10
Abstract: 893,545. Photographic dye-imbibition processes including multi-colour reproduction. KODAK Ltd. July 10, 1958 [July 10, 1957], No. 22181/58. Class 98(2). A silver halide image in an emulsion layer is colour developed to form an image of non- diffusing ionic compound or dye, this image is dyed up with a diffusing ionic dye of opposite charge, and the dyed up layer is placed while moist in contact with a receiving layer containing a mordant for the diffusing dye for image-transfer thereto. In a first form of the invention the coupler is in the developing solution and either coupler or developing agent is anionic or cationic, to form the non- diffusing dye, and the diffusing dye for application thereto is of opposite character. The silver halide image for this may result from direct exposure, bleaching of a silver image in a silver containing relief image as used in imbibition processes, or reversal treatment, and is normally a separation record. In a second form the coupler is in the emulsion and may have an acid group in a non-coupling position and develop to a soluble dye, leaving non-diffusing coupler in non-image areas. Repeated transfers may be made to a single receiving layer to form multicolour image. In Example 1, the first form, a positive film is exposed to a red-light colour-separation image, treated in a developer containing 4- amino - N - (10 carboxydecyl)-N-ethyl-3-methyl aniline and the anionic coupler 1-hydroxy-N- [2 - (#- sulphoethoxy) phenyl]-2-naphthamide, rinsed, fixed, washed, treated in a ferricyanidebromide bleach solution, rinsed, refixed, bathed in methylene blue dye solution, rinsed and placed in contact with a receiving blank having a gelatin coating containing the acid mordant 1 -hydroxy-4-chloro-N- { 4-[2-(2:4-ditert. - amylphenoxy) - 5 - (3 : 5-disodium-sulphobenzamido)-benzamido] - phenethyl} - 2 - naphthamide, which blank had been pre-conditioned with acetic acid, to transfer the dye image thereto. A series of cyan images may be so made by repeating the dyeing, rinsing and transferring steps. Magenta and yellow basic dye images prepared from the green and blue light colour separation images of the same subject are applied to the blank similarly. Examples 2, 3 also transfer methylene blue images, the first of these with use of different coupler and developing agent and the second including reversal procedure. Examples 4, 5 specify cationic dye images for use with acid dyes and a polyvinylaminoguanidine mordant as of Specification 850,281. Example 6 illustrates the second form of the invention with coupler in the emulsion layer and solutions and processing times therefor are fully described. Numerous couplers, colour developers, dyes and mordants are listed. Specifications 654,266 and 804,661 also are referred to.

Title: Improvements in or relating to a process for making rubber thread
IPC: C08J5/02
Filed: 1934-07-31
Abstract: In the production of rubber threads, tubes, rods, and the like by the extrusion of sensitized latex through heated nozzles, the rate of extrusion is increased by bringing the dispersion into the coagulating zone at a temperature approaching that of coagulation. This increases the rate of coagulation and liberates serum which acts as a lubricant between the coagulum and the walls of the nozzle. Lubricants such as glycerine, alkaline soaps, saponin, glucose may also be added for the same purpose.  The dispersion may be heated to 40-60 DEG  C. and cooled prior to the addition of sensitizing agents, or it may be heated after such addition until a slight thickening occurs.  According to an example, 167 gm. of 60 per cent latex are added vulcanizing and antiageing agents suspended in 10 c.c. of water and 12 c.c. of glycerine; 0,5 gm. of ammonium sulphate in 2 c.c. of water and 1,7 gm. of zinc sulphate in 18 c.c. of ammonia solution are added and the dispersion is heated to 50 DEG  C. for an hour to thicken it. Extrusion takes place at a pressure of 0,25 atm. through a nozzle of 2,5 mm. diameter, the first 20 cm. of which is heated to 83-85 DEG  C., and the 10 cm. near the outlet, to 91-93 DEG  C., the coagulating temperature being 87-80 DEG  C.
